Increase your penis size during intercourse with this realistic penis extension system made of soft Cyberskin. This super stretchy sleeve can fit most sizes, giving you 3 inches of extra length. Pull the sleeve over your erect penis and add the cock ring with removable micro-stimulator for a harder and longer lasting erection. Leave the vibrator at the bottom for testicle stimulation, or place it at the top for clitoral stimuli. If you need to adjust the size simply cut the sleeve at the base of the shaft to your specifications. Requires 3 button cell batteries and 6 are included.
